Brew doctor: dyld: Library not loaded & Error: No available formula for zlib

When I brew doctor I get the following errors:

dyld: Library not loaded: /usr/lib/libltdl.7.dylib
  Referenced from: /usr/local/bin/php
  Reason: image not found
Error: No available formula for zlib

The file libltdl.7.dylib is not in my /usr/lib directory, but there are several other .dylib files.

I'm running 10.8.1 with the latest version of Xcode (4.4.1) and its Command Line Tools installed.

Any idea how to solve these errors?

Try to re-install libtool by:

brew reinstall libtool --universal && brew unlink libtool && brew link libtool

If that doesn't help, try removing libtool completely, and then retry the steps above:

brew uninstall libtool

If it still doesn't work after trying the steps above, check to see if you have the DYLD_FALLBACK_LIBRARY_PATH variable defined somewhere on the system (e.g. ~/.profile) and try unsetting it before trying the steps above again.

Other commands which could be useful for identifying the issue:

$ libtool --version
$ whereis libtool
$ set | grep DYLD_FALLBACK_LIBRARY_PATH
$ echo $DYLD_FALLBACK_LIBRARY_PATH

For me it works with:

sudo ln -s /usr/local/Cellar/libtool/2.4.2/lib/libltdl.7.dylib /usr/local/lib/libltdl.7.dylib

Try:

brew tap homebrew/dupes

if you have an error about pcre like this :

dyld: Library not loaded: /usr/local/opt/pcre/lib/libpcre.1.dylib
  Referenced from: /usr/local/Cellar/watchman/4.7.0/libexec/bin/watchman
  Reason: image not found
Abort trap: 6

you need to link pcre.

brew link --overwrite pcre

xcode-select --install
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install pcre
brew install libtool

that's it.

In my case I solve it with this link's file:

ln -s /usr/local/Cellar/jpeg/8d/lib/libjpeg.8.dylib /usr/local/opt/jpeg/lib/libjpeg.8.dyli

The response from kenorb is what worked for me + a little extra for safe measure: brew update freetype didn't have symlinks so: brew link freetype various other solutions I tried:

brew remove imagemagick
brew link jpeg libpng
brew install imagemagick
brew install libtiff
brew uninstall libtool
brew reinstall libtool --universal && brew unlink libtool && brew link libtool

There's a good chance that this wasn't all necessary if I had found

brew uninstall libtool
brew reinstall libtool --universal && brew unlink libtool && brew link libtool

first. But I thought I would post my full process in case anyone runs into issues

For me, I needed to fix XQuartz as brew doctor asked me too:

Warning: Your XQuartz (2.7.6) is outdated Please install XQuartz 2.7.8: https://xquartz.macosforge.org

It worked after that.

I experienced the same error in the process of installing AFNI. Installing PyQt, as suggested here, fixed the issue resulting from OSX 10.11 compatibility.

brew install pyqt

I had: % neato dyld: Library not loaded: /usr/lib/libltdl.7.dylib Referenced from: /Users/me/Documents/dev/anaconda/bin/neato Reason: image not found zsh: abort neato

And the fix was % echo $DYLD_FALLBACK_LIBRARY_PATH /Users/me/anaconda/lib:/usr/lib % export DYLD_FALLBACK_LIBRARY_PATH=$DYLD_FALLBACK_LIBRARY_PATH:/usr/local/lib

(and then add the export to a .bashrc or similar).
